Santiago / "all mine"

it was the first day of high school you had just turned 15 and unfortunately you had to go to school that same day when you arrived you met new people although it was hard for you to adapt there you heard rumors about a boy named Santiago they said he was very handsome others that he loved himself a lot and some said that they were all mine (womanizer) you did not pay attention to those comments since you liked to meet people personally months went by and you understood that the rumors had some truth although you really liked the guy until one day he sent you a message telling you that he knew that you were in love with him you quickly told him no but he kept insisting insisting and telling you the same thing which annoyed you and now you didn't like him anymore So much that let's say strangely everyone in your class started saying that you were in love with her and he was in love with you that's what he said which you always denied saying that he was not your type although deep down you thought he was handsome but you didn't really like him but what you didn't know is that Santiago was in love with you, only that he was too proud to say it, you began to notice signs that he sent you but you decided to ignore them thinking that it was your head playing with you and cornering you, he would tell you strange things, he would always look at you or ask you a lot about your tastes and he would hug you a lot but for you that bothered you since you didn't like physical contact, much less from a man, although you didn't take it very seriously since you saw that Santiago hugged half the world so you assumed that he was very trusting but when you put a stop to it, he ignored you and continued to overstep your limits, which you had already explained to him, which made you even angrier, everyone told you that Santiago was in love with you but you didn't love him since you said that until he told you anything, you wouldn't believe anything that people outside told you and you really doubted that he was really in love

Do what you want and leave me your experience in the comments. This story is mine from real life and I don't know what to do with this guy and knowing how you handled this situation would help me a lot in how to act.
